How about packaging a Reseller's' domains? Reseller can then offer his customers sub-domains, for example,http://customer.reseller.com
You can charge reseller for each sub-domain. The sub-domain will only have the mini interface,same as the present.

Finally this feature has been implemented. Here are the instructions to get your own domain name for the mini interface:

Buy a domain name. You can buy a domain name from services called registrars. Two popular registrars are GoDaddy and Network Solutions. Make sure the registrar you use offers custom DNS services. At GoDaddy, it's called 'Total DNS Control' and at Network Solutions it's called 'Advanced DNS.'

Go to your registrar. Follow the link to either Total DNS Control or Advanced DNS. In this option, change only the CNAME to the data center where the accounts of your clients reside. This might be something like, http://www2.pbxes.com. In this step, you are telling your registrar where to point your domain name. (The feature is available in all of our data centers except the newest one in Tokyo which has not been upgraded yet.)

Wait. It may take up to 2 days for your registrar to point your domain name to PBXes.

If you want your domain co-branded with your own logo (next to the PBXes logo) this is also possible. For adding your logo please:

When configuring the SIP phone, can I use the SIP server as sip.mydomain.com instead of sip.pbxes.com? I would like to use my own domain name as the sip server. If there would be extra charge, let me know how much.

Do you mean that it only needs a SRV entry to my DNS record of my domain and there's no configuration needed at pbxes? My hosting provider did a CNAME entry for me to point my domain to pbxes, so please let me know what's needed for the SRV entry, so that I can check with my provider whether they can do it.

You should register to paid accounts only when using a custom domain as SIP server. There is no additional fee.

A SRV entry is not required for SIP servers. It's used for receiving calls by SIP URIs. You can add a SRV entry in the same fashion as the one of pbxes.org. This is really non trivial. By reading out ours you learn how to verify your own.

Resell the service
We want to resell the service to our local business customer.
We have read most of the thread regarding this.
But we still got some thing want to clear:
1. If just “premium account” can we resell or can we resell all of the account just premium account got discount?
2. the resale discounted rate is only one time for us or lifetime for us keep this customer?
3. If all our our customer pay us and we will use one Payapl account to pay you? OR all customer have to pay you directly use Paypal?
4. for blacklisting, if we never have free account. All of accounts will be paid accounts. So, there is no blacklisting for us?
5. customized: What can we do for it? If all of our customer will have the user interface with our logo + PBXes logo? This look like white label reseller?
